LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a high energy beam of light which is used to treat the eyes in various ways. LASERs used in the OPD (Out-patient department) are mainly used for the management of retinal and anterior segment conditions.
Retinal LASER:
These are done usually to the swelling in the central part of the retina (Macular oedema), for areas of ischaemia in retina especially when abnormal new vessels are formed or to weak areas in retina (holes, tears).
